Weekend storm looms

Marin's weather is a bit up in the air, but if a high pressure system breaks down, allowing a low pressure system to move in, forecasters expect a wet weekend.

National Weather Service forecaster Diana Henderson said that if the two weather systems collide, Marin may be in line for a half-inch or so of rain as well as gusty winds, sometime Saturday, probably in the afternoon. Showers could drizzle into Sunday.

"There is an upper-level low meandering down the coast ... and if our high-pressure system breaks down ... it could rain," she said.

Storm clouds will be gone by Sunday evening, and dry weather is expected next week, she added.

Temperatures logged by federal forecasters indicated a 32-degree low in Kentfield Wednesday, and 33 in San Rafael, although Henderson said other locales in Marin have been even colder. Marin cold spots will warm slightly over the next several days.
